first solver you try ode45 Medium SolverAccuracy Description Runge-Kutta (4,5) formula *No precise definition of stiffness, but the main idea is that the equation includes some terms that can lead to rapid variation in the solution.
22.01.2021 · This function implements a fixed-step Runge-Kutta solver for explicit and implicit methods (and with optional adaptive step size control). The function supports both explicit and implicit methods, and embedded methods as well. Any Runge-Kutta method can be added simply by specifying their butcher tableaus.

Lecture 12: Solving ODEs in Matlab Using the Runge-Kutta Integrator ODE45() Example 1: Let’s solve a first-order ODE that describes exponential growth dN dt =aN Let N = # monkeys in a population a = time scale for growth (units = 1/time) The analytical solution is N(t)=N0eat-The population N(t) grows exponentially assuming a > 0.
Runge-Kutta Method – Numerical Differentiation with MATLAB Runge-Kutta method is a famous numerical method for the solving of ordinary differential equations. This method was developed in 1900 by German mathematicians C.Runge and M. W. Kutta. The RK method is valid for both families of explicit and implicit functions.
All MATLAB ® ODE solvers can solve systems of equations of the form y ' = f (t, y), or problems that involve a mass matrix, M (t, y) y ' = f (t, y). The solvers all use similar syntaxes. The ode23s solver only can solve problems with a mass matrix if the mass matrix is constant.
